Is is possible to do expansion when exporting variables?

[vext01]

I have no idea if POSIX says anything about this, but I notice a discrepancy between yash and other shells:

bash

$ export A=~
$ echo $A
/home/edd

(similarly for zsh`` and pdksh`)

yash

$ export A=~
$ echo $A
~

I noticed this when adding things to the path. If ${PATH} contains an unexpanded ~ then it the path isn't searched as one may expect.

Is yash doing the right thing? Can it be made to behave like other shells?

Thanks.

The current POSIX does not require the bash behavior, but it will in the future. This feature is tracked in #20.

For now, you can use a separate assignment to make ~ expand:

A=~
export A
echo $A
